User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release)
Build ID: 20130511120803

Steps to reproduce:

I created a handful of elements and made them red (#ff0000) in various ways, using:

* CSS
  * background-color: #f00
  * background: linear-gradient(#f00, hsla(0, 100%, 50%, 1))
  * background: radial-gradient(#f00, hsl(0, 100%, 50%))
  * background: url(no-profile.png) // image with no colour profile
  * background: url(embedded-profile.jpg) // image with with colour profile
* Canvas
  * c.fillStyle = '#f00'; c.fillRect(0, 0, 200, 200);
* SVG
  * fill: rgb(255, 0, 0)
* Image
  * <img src="no-profile.png"> // image with no colour profile
  * <img src="embedded-profile.jpg"> // image with with colour profile

I have set gfx.color_management.mode to 1 (full colour management) and have a properly calibrated wide gamut monitor.

Here is a test page that demonstrates this: https://dl.dropboxusercontent.com/u/41899939/colour-management.html


Actual results:

The boxes with with colour set by linear-gradient, radial-gradient and a canvas displayed with a very vivid red (i.e., without colour management). The rest were showing the correct red.

Here's a screenshot, with an embedded profile (the differences may not be visible on your screen): https://dl.dropboxusercontent.com/u/41899939/screenshot-embedded-profile.jpg

Here's another screenshot, as sRGB with no embedded profile (the colours aren't right, but on my screen, imagine the orange squares are red, and the red ones are a very vivid red): https://dl.dropboxusercontent.com/u/41899939/screenshot-srgb.jpg


Expected results:

All of the boxes should appear to be the same colour.

Looks like this is still the case in Firefox 66.0.3 on macOS 10.14.4:

Both canvas charts are using the same fill and stroke styles, yet the Firefox's image (on the right) appears a lot more saturated than Chrome's.
